* 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.

* 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.

* Allow configuring forwards-table columns, order, and width
Adds an optional tui.columns section to .kportal.yaml so the visible
columns, their order, and their widths can be customized instead of
always rendering the hardcoded 8-column layout. Omitting the section
keeps the existing default columns/order/widths.
Closes#81
* fix(ui): keep the plain table layout and check column widths
The plain verbose table must look the same when no tui section is
set. It had narrower columns and shorter port headers than before. The
default layout is now identical to the old one, and a golden test
guards it.
A status column that is not last now pads by visible width. Table
rules follow the column widths. The UI applies new columns only after a
reload succeeds, including the SIGHUP path of the verbose table.
The validator rejects a column width above 200. The README describes
the tui.columns setting.

* fix(httplog): replace the deprecated ReverseProxy Director with Rewrite
Staticcheck reports SA1019 because Go 1.26 deprecates Director. The
proxy now sets the target in a Rewrite function. Rewrite drops the
X-Forwarded-For header that Director sent, so the function calls
SetXForwarded to keep that header.
A new test checks the target port, the path and the header.
* fix(release): drop the deprecated cask url verified key
Homebrew warns about the verified parameter of the cask url stanza.
The setting is not needed. GoReleaser check now passes without a
deprecation warning.
The postflight warning remains. GoReleaser generates it from the
post install hook, and the upstream fix is not released yet.

Real kubeconfig context names commonly contain characters the
validator rejected:
- 'admin@home', '[email protected]' (kubectl rename, EKS
aws-iam-authenticator)
- 'cluster.example.com', 'gke_proj_zone_cluster.prod' (FQDN, GKE)
- 'arn:aws:eks:us-east-1:123:cluster/foo' (EKS ARN)
kubeconfig itself imposes no character restrictions, so requiring
[a-zA-Z0-9_-] only was kportal-specific over-validation that blocked
legitimate users. Widen the allowed set to add '@', '.', ':', '/'.
Names must still start and end with a letter or digit so YAML
specials and leading whitespace remain rejected.
Tests cover the new positive cases and tighten negative coverage
(starts-with-@, ends-with-/, ends-with-dot).
When user starts kportal for the first time, and there is no config file,
kportal should create an empty config file with default values and empty
forwarding rules, so that user can easily edit the config file and add their
own rules.
