chore(deps): upgrade typescript 5.9.2 to 6.0.3

[davidfirst]

Bumps typescript to the latest stable major (6.0.3). Small set of compatibility adjustments to absorb TS 6's new stricter defaults without changing behavior for downstream users on TS 5.x.

• workspace.jsonc: bump typescript pin in root policy and in the scopes/harmony/bit variant.
• Root tsconfig.json (repo-internal only, not shipped): add ignoreDeprecations: "6.0", set noUncheckedSideEffectImports: false, and list types: ["node", "mocha", "chai", "jest"] to restore the pre-6 auto-discovery behavior for test specs.
• scopes/typescript/typescript/typescript.main.runtime.ts: in createCompiler, auto-inject ignoreDeprecations: "6.0" when the loaded typescript is major version ≥ 6 and the caller hasn't set it. This keeps the shipped env tsconfigs (scopes/react/react/typescript/*.json, scopes/harmony/aspect/typescript/tsconfig.json, scopes/typescript/typescript/tsconfig.default.json) untouched so they remain valid for TS 5.x consumers — TS 5.x rejects ignoreDeprecations: "6.0" with TS5103, and TS 5.x rejects moduleResolution: "bundler" + module: "commonjs".

Test plan

• bit compile — 311/311 components compile
• npm run lint — 0 tsc errors, 0 oxlint warnings across 2,838 files
• CI e2e

Pull request overview

Upgrades the repo’s pinned TypeScript version to 6.0.3 and applies targeted configuration/runtime adjustments so the workspace can compile/lint cleanly under TS 6 while keeping shipped env tsconfigs compatible with TS 5.x consumers.

Changes:

• Bump typescript pin from 5.9.2 → 6.0.3 in the root dependency policy and the scopes/harmony/bit variant.
• Update the repo-root tsconfig.json with TS 6 compatibility settings (ignoreDeprecations, noUncheckedSideEffectImports, and explicit types).
• Update TypescriptMain.createCompiler() to auto-inject ignoreDeprecations: "6.0" only when the loaded compiler is TS 6+ and the caller didn’t set it.

Pull request overview

Upgrades the repo’s pinned TypeScript version to 6.0.3 and adds targeted configuration/runtime shims so Bit’s shipped TypeScript env configs remain compatible with TS 5.x consumers while the repo itself builds with TS 6.

Changes:

• Bump typescript pin to 6.0.3 in workspace.jsonc (root + harmony/bit variant).
• Update root tsconfig.json with TS6-related options (ignoreDeprecations, noUncheckedSideEffectImports, explicit types list).
• Patch TypescriptMain.createCompiler() to inject TS6-only compiler options at runtime when the loaded compiler is TS 6+.

Pull request overview

Upgrades the repository’s TypeScript toolchain to TS 6.0.3 and applies compatibility shims/config tweaks so TS 6’s stricter defaults don’t unintentionally change behavior (especially around deprecations, side-effect imports, and ambient type discovery).

Changes:

• Bump typescript from 5.9.2 to 6.0.3 in workspace.jsonc (root policy + harmony/bit variant).
• Update root tsconfig.json with TS6-focused options (ignoreDeprecations, noUncheckedSideEffectImports, explicit types).
• Patch TypescriptMain.createCompiler() to conditionally adjust compilerOptions at runtime when running under TS 6+.

Pull request overview

Upgrades the repo’s pinned TypeScript version to 6.0.3 and adds targeted compatibility shims/config tweaks so the workspace and shipped Bit TypeScript envs continue to behave as before (especially around TS6’s stricter defaults).

Changes:

• Bump TypeScript pin to 6.0.3 (root policy + scopes/harmony/bit variant) and add an explicit @types/jest pin.
• Update root tsconfig.json to absorb TS6 defaults (ignoreDeprecations, noUncheckedSideEffectImports, explicit types list for test globals).
• Patch TypescriptMain.createCompiler() to apply TS6-only runtime tsconfig adjustments (without breaking TS5.x consumers of shipped env tsconfigs).
• Update an e2e fixture to explicitly set strict: false to keep the test intent stable under TS6.

workspace.jsonc:405

• @types/jest is pinned to 26.0.20, but this workspace also pins jest to 29.3.1. Keeping Jest runtime and its type package on different majors can lead to missing/incorrect typings (especially for newer Jest APIs) and make test type-checking less reliable. Consider updating @types/jest to a 29.x version that matches the Jest major (or, if the intent is to avoid full Jest typings, document why this older major is intentionally pinned).
