lukaszraczylo f7287b3ef6 refactor(ui): migrate to bubbletea v2 and lipgloss v2
Switch imports to charm.land/bubbletea/v2 and charm.land/lipgloss/v2.
View now returns tea.View with AltScreen set, key handling uses
KeyPressMsg, and colour fields use image/color.

4d263319ab feat: add --context to forward only selected contexts (#85)
* feat: add --context to forward only selected contexts

kportal forwards every context in the config file. When the file describes
several clusters that host the same services, that means holding connections
open to clusters nobody is using, and - because all contexts are active at once
- every localPort has to be globally unique. The same service therefore lands on
a different local port per cluster, so switching clusters means reconfiguring
the app being developed.

--context limits a run to the contexts you name. It is repeatable and accepts
comma-separated values, and composes with -headless:

    kportal --context development-team-a
    kportal --context team-a,team-b -headless
    kportal --context team-a --context team-b

An unknown name is an error listing the contexts the file defines, so a typo
fails loudly instead of silently forwarding nothing.

Local-port and mDNS-hostname conflicts are now scoped to forwards that could run
at the same time: same context, or both contexts in the active selection. With
no selection every context is active, so existing behaviour is unchanged.
Contexts that are never selected together may reuse the same localPort, which is
what lets a service keep one fixed local port in every cluster.

Validation still covers the whole file, so a problem in a context outside the
selection is still reported and --check does not get weaker. Loading, validating
and filtering are shared by every path that re-reads the config (startup, file
watcher, SIGHUP in both headless and verbose modes), so no path can forget the
selection.

Also fixes a latent identity bug this makes reachable: Forward.ID() is only
"alias:localPort" when an alias is set, which was unique across contexts only
because duplicate local ports were globally rejected. With ports now shareable,
deleting or editing a forward from the TUI could have matched same-alias
forwards in other contexts and silently removed them. Delete and edit are now
scoped to the context the row came from.

* fix(config): keep the running config when no selected context remains

A reload dropped selected contexts that no longer exist in the file.
When all of them vanished, the reload returned an empty config and the
manager stopped every forward after a single rename.

LoadForRuntime now returns an error in that case. The watcher keeps the
previous config, as it does for any other invalid reload.

Refs #80

* fix(ui): apply new table columns after a successful SIGHUP reload

The context selection moved the SIGHUP reload into reloadFromSignal,
which had no way to update the verbose table columns. The function now
takes a callback that runs only after the manager reloads without error.
The verbose table passes SetColumns.

lukaszraczyloandGitHub 4748bc4be5 feat(ui): type the namespace when the cluster does not list them (#84)
Some users cannot list namespaces on a cluster. The add wizard showed
an error and offered no way forward.

The namespace step now switches to a text prompt when the list call
fails or returns nothing. The prompt shows the reason and checks that
the name is a valid DNS label. Esc from a later step returns to the
prompt.

The j and k keys now type into text fields. They moved the list cursor
before, so a name such as kube-system could not be typed.

Closes #66

lukaszraczylo dbc7830546 fix(ui): edit-mode wizard allows keeping the same local port
Previously, editing a forward and keeping its local port unchanged
failed the wizard's port-availability check: the in-config scan
found the forward's own entry and reported '✗ Port N already
assigned to <self.ID>'. Users had to pick a different port,
edit, then change back.

checkPortCmd now accepts an excludeID. The wizard passes
wizard.originalID when isEditing so the forward being edited is
ignored during the in-config conflict scan. The OS-level port
check is unchanged (still catches actual port collisions).

New regression test: TestCheckPortCmd_ExcludeID_AllowsKeepingOwnPort.

lukaszraczylo bfe541565b feat(ui): toggle httpLog per-forward in add/edit wizard
Adds an HTTP-log enable toggle to the wizard's confirmation step so
users can flip httpLog on a forward without editing YAML by hand.

Behaviour:
- 'h' on the confirmation step toggles HTTPLog when not focused on
  the alias text input. When focus is on alias, 'h' is treated as
  text so users can still type aliases like 'host' or 'http-proxy'.
- The confirmation summary shows '[x] enabled' or '[ ] disabled'.
- New forwards: toggle on -> &HTTPLogSpec{Enabled: true}; off -> nil.
- Edit mode: pre-populates the toggle from the existing forward and
  preserves any advanced HTTPLog fields the user had configured in
  YAML (logFile, includeHeaders, maxBodySize, filterPath) by copying
  the original spec on save. Toggling off discards the advanced
  fields (consistent with 'absent in YAML = disabled').

State changes:
- ForwardStatus gains *config.HTTPLogSpec so the wizard can see the
  full original spec on edit.
- AddWizardState gains httpLog bool + httpLogOriginal *HTTPLogSpec.

Three new tests:
- TestHandleAddWizardKeys_HToggleHTTPLog
- TestHandleAddWizardKeys_HOnAliasFocusIsTextInput
- TestEditPrefill_PreservesHTTPLog

lukaszraczylo 4fe3f6b21f fix(ui): Esc cancels delete confirmation instead of confirming it
In the remove-wizard's confirming state, pressing Esc was reflexively
calling removeForwardsCmd — i.e. confirming deletion. The on-screen
help text said 'Esc: Cancel'. Reflexive Esc-to-cancel destroyed data.

Esc now sets confirming=false and resets the cursor; deletion
requires Enter on Yes. Non-confirming Esc behavior (exit wizard with
ClearScreen) is unchanged.

Three regression tests added in handlers_test.go.

lukaszraczylo b7a32e4aab Port forward to the named service ports.
When adding a service via the wizard, resolve the service's targetPort to the actual pod container port instead of using the service port directly.
Problem: Service port 80 → Pod port 8000, but kportal was trying to forward to port 80 on the pod.
Solution: Look up the pod's actual containerPort when the service uses a named targetPort (like http), and use that for port-forwarding.
